You can make this cleanup of the system properties more robust by using the
`RestoreSystemProperties` JUnit rule. All you need to do is add this as a
member variable of the test class:
```
@Rule
public final RestoreSystemProperties restoreSystemProperties = new
RestoreSystemProperties();
```
(For an example see
[LocatorLauncherTest](https://github.com/apache/geode/blob/d1db2f02d2ce45a437b34488934e5b1d53c7b5ca/geode-core/src/test/java/org/apache/geode/distributed/LocatorLauncherTest.java).)
